There are specific cognitive functions necessary to safely drive a vehicle that can be impacted by alcohol, drugs, fatigue, or other sources. There is currently not a roadside assessment that can detect driver impairment regardless of the source. The iPad Roadside Sobriety Test project is exploring the use of cognitive tasks as an assessment tool for driver impairment to resolve this problem. We are currently investigating the diagnostic ability, reliability, and validity of different cognitive tasks for the impairment of cognitive functions essential for driving.
The Georgia Tech Sonification Lab is an interdisciplinary research group based in the School of Psychology and theSchool of Interactive Computing at Georgia Tech. Under the direction of Prof. Bruce Walker, the Sonification Lab focuses on the development and evaluation of auditory and multimodal interfaces, and the cognitive, psychophysical and practical aspects of auditory displays, paying particular attention to sonification. Special consideration is paid to Human Factors in the display of information in "complex task environments," such as the human-computer interfaces in cockpits, nuclear powerplants, in-vehicle infotainment displays, and in the space program.
[Random Image of Auditory Interface] Since we specialize in multimodal and auditory interfaces, we often work with people who cannot look at, or cannot see, traditional visual displays. This means we work on a lot of assistive technologies, especially for people with vision impairments. We study ways to enhance wayfinding and mobility, math and science education, entertainment, art, music, and participation in informal learning environments like zoos and aquariums.
The Lab includes students and researchers from all backgrounds, including psychology, computing, HCI, music, engineering, and architecture. Our research projects are collaborative efforts, often including empirical (lab) studies, software and hardware development, field studies, usabilty investigations, and focus group studies.
